目的本研究旨在确定替代元音空间面积 (VSA) 测量（即基于轨迹的新颖测量：元音空间外壳面积和元音空间密度）对构音障碍说话者预测语音清晰度的程度是否与两种传统元音测量（即基于标记的测量：VSA 和角分散度）相同。此外，本研究还检验了声学元音测量与可懂度之间关系的强度是否因可懂度测量方式（即正字法转录 [OTs] 和视觉模拟量表 [VAS] 评级）的不同而不同。 方法 由 40 名患有不同病因的构音障碍的说话者大声朗读《祖父通道》，包括帕金森病 (n= 10)、肌萎缩侧索硬化症 (n= 10)、亨廷顿病 (n=10) 和小脑性共济失调 (n=10)。根据段落计算基于标记和轨迹的声学元音测量。通过众包招募新手听众（N = 140）来提供 OT 和 VAS 清晰度评级。创建分层线性回归模型，使用声学元音测量作为预测因子来对 OT 和 VAS 清晰度评级进行建模。结果传统 VSA 是 OT (R2= .259) 和 VAS (R2= .236) 模型的语音清晰度的唯一显着预测因子。相比之下，基于轨迹的测量并不是清晰度的显着预测因素。此外，OT 和 VAS 清晰度评级传达了类似的信息。结论研究结果表明，传统的基于标记的元音测量比基于轨迹的测量更好地预测清晰度。此外，研究结果表明，出于研究目的评估语音清晰度时，VAS 方法与 OT 方法相当。
PurposeThis study sought to determine if alternative vowel space area (VSA) measures (i.e., novel trajectory-based measures: vowel space hull area and vowel space density) predicted speech intelligibility to the same extent as two traditional vowel measures (i.e., token-based measures: VSA and corner dispersion) in speakers with dysarthria. Additionally, this study examined if the strength of the relationship between acoustic vowel measures and intelligibility differed based on how intelligibility was measured (i.e., orthographic transcriptions [OTs] and visual analog scale [VAS] ratings).MethodThe Grandfather Passage was read aloud by 40 speakers with dysarthria of varying etiologies, including Parkinson's disease (n= 10), amyotrophic lateral sclerosis (n= 10), Huntington's disease (n= 10), and cerebellar ataxia (n= 10). Token- and trajectory-based acoustic vowel measures were calculated from the passage. Naïve listeners (N= 140) were recruited via crowdsourcing to provide OTs and VAS intelligibility ratings. Hierarchical linear regression models were created to model OTs and VAS intelligibility ratings using the acoustic vowel measures as predictors.ResultsTraditional VSA was the sole significant predictor of speech intelligibility for both the OTs (R2= .259) and VAS (R2= .236) models. In contrast, the trajectory-based measures were not significant predictors of intelligibility. Additionally, the OTs and VAS intelligibility ratings conveyed similar information.ConclusionsThe findings suggest that traditional token-based vowel measures better predict intelligibility than trajectory-based measures. Additionally, the findings suggest that VAS methods are comparable to OT methods for estimating speech intelligibility for research purposes.
